Struct PrefixCode 

pub struct PrefixCode { /* private fields */ }

A (possibly non-canonical, possibly incomplete) binary prefix code.

Implementations

impl PrefixCode

pub fn new(codes: &[(u32, u32, u32)]) -> Result<Self>

Build from (code, length, value) triples; code is right-aligned.

pub fn walk(&self, prefix: u32, nbits: u32) -> Option<(u32, u32)>

Walk the code with the nbits most significant bits of prefix (left-aligned in nbits): (code length, value) if a leaf is reached within them.

pub fn decode<B: BitRead>(&self, bits: &mut B) -> Result<u32>

Decode one symbol.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PrefixCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result
